I forgot to change it here.  It should have been

Info: never output text before the first @node or sectioning command.

The @-command are processed, but no output is produced (or the output is
hidden).

Here is an example.

What I propose is
* in book-like: output, in some way, some @titlepage content and @copying.
  not output "Before node and sectioning. Not output in Info."
* in non book: not output "Before node and sectioning. Ignored in Info."

In every case, process "@documentlanguage l1" and "@documentlanguage l2",
whatever is output or not output.





\input texinfo.tex

@c preamble

@copying
This is foo. Conditions.
@end copying

@titlepage
@title Title

@page
@insertcopying
Some publishing informations
@end titlepage

@frenchspacing on

@c after preamble, before @node and sectioning commands
Before node and sectioning. Ignored in Info.

@documentlanguage l1

@top Something
@node Top

This is foo. Ignored in printed.

@documentlanguage l2

@node another node

Always output.

@node Chap
@chapter Chap


@bye
